Surface morphology and magnetic anisotropy of Fe/MgO(001) films deposited at oblique incidence
Qing-feng Zhan, Chris Van Haesendonck, Stijn Vandezande +1
We have studied surface morphology and magnetic properties of Fe/MgO(001) films deposited at an angle varying between 0o and 60o with respect to the surface normal and with azimuth…
Monolayer Characteristics of Pyrene Mixed with Stearic Acid at the Air-Water Interface
Md. N. Islam, D. Bhattacharjee, Syed Arshad Hussain
In the present communication we report the monolayer characteristics of pyrene mixed with stearic acid (SA) at the air-water interface. The monolayer properties are investigated by…
Photoluminescence from localized states in disordered indium nitride
Bhavtosh Bansal, Abdul Kadir, Arnab Bhattacharya +1
Photoluminescence spectra from disordered InN were studied in very high magnetic fields. The samples had Gaussian spectra with low temperature emission peaks at 0.82 and 0.98eV res…
Chemical Bonding in the Boron Buckyball
Arnout Ceulemans, Jules Tshishimbi Muya, G. Gopakumar +1
A symmetry analysis of the valence shell in the boron buckyball B80, shows a perfect match with the symmetry of the valence shell in C60 .The cap atoms participate in the bonding b…
Magnetic states and spin-glass properties in Bi0.67Ca0.33MnO3: macroscopic ac measurements and neutron scattering
M. Giot, A. Pautrat, G. Andre +3
We report on the magnetic properties of the manganite Bi_{1-x}Ca_{x}MnO_3 (x=0.33) at low temperature. The analysis of the field expansion of the ac susceptibility and the observat…
Small angle neutron scattering study of the step-like magnetic transformation in Pr0.70Ca0.30MnO3
D. Saurel, Ch. Simon, A. Brulet +2
Small angle neutron scattering (SANS) magnetic and electrical transport measurements were performed to study a single crystal of Pr0.7Ca0.3MnO3, a colossal magnetoresistive (CMR) m…
